WhatI claim is:- l

1. A valve comprising a casing'havingl ports disposed side by side, atended into `said casing 'and ividi'ngthe two tively with said portsjandplfii'vtl-l ing ing a c amber within said casing at"g the 'inl-1 nerends of said passageway, aconclve seat formed upon the lower portion ofsaid easing and adapted 'to receive'an apertured portion of a pipe, andan oscillatory late mounted in the plane of the top oisai arranged -toclose the a erture in saidv pipe, s id plate being mova le to aItransverse p ane whereby one edge engages'said4 partition and dividessaid chamber.

2. A valve comprisin a casing'e-{having two ports. disposed side y side,apartition.-

extended into said casing and dividing the interior into two assagewayscorni'mxnicating res ctive'ly 'with said portsandprbvid# ing a c amberwithin said casing at the ingas into the heater.

passageways e'omniunicab v isa ner ends of said passageways, a concaveseat formed upon the lower portion of said casing andprovided with anopenin a valve plate pivoted intermediate its enge in said aperture.whereby said late is movable tea position to close saidpopenin and to alateral position to divide said c amber.

3. A valve comprising a casinhaving a plurality of passageways theretrou h, a plurality of stubs communicating. wit the respectivepassageways a transversely pivoted plate at the en s of, saidpassagewaysopsosite said studs and movablelto open an close 'the same,and rotatable means upon which said plate is mounted wherebyvsaidplatais movable to'a position to close the inner ends of said passa waysand to a transverse position to' provi e continuations of saidpassageways within said casing.

4. A valve comprising a casing, a dis clia'rge stub therefor, a returnstub adjacent said discharge stub, a web within said casing providingpassa eways leading to said stubs and a pivote flat valve platecontrolling the ends of said pasageways o posite said stubs, said plateadapted to hb seated against said web to.permit a flow through saidpassageways and movable t0 a position across the end ,of bothpassageways to close the same.

5. The combination with a feed pipe hav` ing an elongated openingtherein, of a valve casing engaging t e pipe and surrounding saidopeningraiid having an aperture in sage-waysand movab registrytherewith, said casing havin' a discharge and a return passageway botcominunicating with said o enin and a valve plate pivotally mounte in tel aperture in said casing and movable into one position to close .saidcasing a erture and said pase inw another position to extendtransversely across said pipe` in said pi is whereby the fluid movingv hth to itt roug e taken from it and returne casin 6. fn combination ,witha pipe having van aperture therein, aneasing having an aperturecoinciding with the aperture in saidpi e, a valve plate closing theaperture 'in sa d casin e spindle mounted transversely across saiaperture upon which said plate is secured, and stubs leading from saidcas- .ing and o ing into 4.siiid pi e on opposite sides of t e pivot ofs'aid p ate.-

7. In combination'with a pipe having an aperture therein; a casingvhaving an a rture eoincidin' with the aperture of sai pipe anarchedseat within said easing above sai aperture, stubs leading fromsaid casing and openin into said pipe, plate opera 1e in the aperture insaid casing, said valve movable into one position to close said apertureand into another position tc provide a plurality of passageways withinsaid easing.
